Reactivity Completes WS-Security Interoperability Testing with Windows Communication Foundation; Company's XML Gateways Interoperate with Windows Communications Foundation, Further Increasing The Value of XML-Enabled Networking for .NET Environments.

BELMONT, Calif. -- Reactivity(R), Inc., a leading XML enabled networking solutions provider, today announced successful completion of interoperability testing with WS-Security and Microsoft's Windows Communications Foundation (WCF). WCF is a part of WinFX, Microsoft's managed code programming model included in Microsoft's next generation operating system, Windows Vista. Completing and passing interoperability testing with WCF ensures that Reactivity's award-winning XML Gateways are compatible with WCF within the .NET environment--a popular backbone for SOA development initiatives.

"Participation in the WCF Interop Plugfests demonstrates broad industry support for secure Web services interoperability based on the WS-architecture," said Ari Bixhorn, director, WinFX Strategy at Microsoft Corp. "We are excited to have Reactivity's involvement and thrilled with the successful interoperability results."

"Reactivity has a long history at the forefront of innovation in XML-enabled networking. Working directly with Microsoft, we are delivering interoperability with WCF and with WS-Security, prior to the standard's ratification, ensuring that our customers with .NET and heterogeneous environments can take instant advantage of WCF," said Andrew Nash, chief technology officer, Reactivity.

Reactivity continues to receive widespread praise for its solutions in real-world applications and test environments. Recently, Reactivity prevailed over Actional, DataPower (acquired by IBM), Forum Systems and Sarvega (acquired by Intel) in a comparative review published in Business Communications Review. Other awards include a SearchWebServices.com "Product of the Year" Award and Software Development's Jolt Productivity Award in the Security Tools category.
